Description

Technical Field

[0002] The fresh air system is an important means of ventilation in modern buildings. It realizes the circulation and renewal of indoor air by introducing fresh air from outside and exhausting the dirty air from inside. In the fresh air purifier with intelligent photocatalyst sterilization module, the fresh air system is the first step of air purification, responsible for introducing fresh air from outside into the room, providing a basis for the subsequent purification process.

[0003] At present, the traditional fresh air purifier with intelligent photocatalyst sterilization module introduces fresh air from the outside through the fresh air system, and removes large particles and impurities in the air through layers of filtration such as primary filter and medium filter. The filtered air enters the photocatalyst sterilization module. Under the irradiation of ultraviolet light or visible light, the photocatalyst produces a strong photocatalytic degradation function, and then sends the fresh air into the room to form a comfortable indoor environment. During long-term use, the primary filter and the medium filter will be attached with a lot of dust, which needs to be cleaned. However, in actual operation, when disassembling and installing the filter, specific auxiliary tools such as screwdrivers and wrenches are often required. This not only increases the complexity of the operation, but also may cause damage to the filter due to tool mismatch or improper operation.

Through the design of the square shell 12, since the surface of the square shell 12 is provided with a square hole, and the push rod 16 can be inside the square hole, the square shell 12 will not interfere with the rotation of the push rod 16, thereby allowing the square shell 12 to move smoothly.

[0043] like Figure 6 and Figure 8 As shown, there are two hinged rods 29 , and the hinged rods 29 are designed to be longitudinally symmetrical about the center of the push plate 30 . The sliding block 14 is designed to be cylindrical, and its surface fits the inner wall of the annular hole 17 . The surface of the sliding block 14 is designed to be smooth.

[0044] The above scheme is adopted: through the design of the hinged rod 29, since there are two hinged rods 29 and they are symmetrically designed, the two hinged rods 29 can smoothly push the push plate 30 and the hinge plate 31 to move, and through the design of the sliding block 14, since the surface of the sliding block 14 is smoothly designed and fits with the inner wall of the circular hole 17, when the push rod 16 rotates, the sliding block 14 can move more smoothly inside the circular hole 17.

[0047] When the primary filter 5 and the medium filter 6 need to be replaced, the sealing plate 42 can be rotated to expose the primary filter 5 and the medium filter 6, and then the motor 18 can be driven to rotate the gear 2 19, and the gear 2 19 will drive the gear 15 and the push rod 16 to rotate. When the push rod 16 rotates, the sliding block 14 will move inside the annular hole 17, and then the push rod 16 will push the moving rod 13, the connecting plate 120 and the limit block 21 to move upward, and then the limit block 21 will move out of the limit hole 22, and then the limit on the primary filter 5 and the medium filter 6 will be cancelled. When the primary filter 5 and the medium filter 6 are moved to the right, the compressed spring 27 pushes the slider 26 and the hinge block 28 to move relative to each other, and then the hinge block 28 drives the hinge rod 29 to rotate, and then the hinge rod 29 is rotated to push the push plate 30 and the hinge plate 31 to move right, and then the push plate 30 pushes the primary filter 5 and the medium filter 6 to move right, and the primary filter 5 and the medium filter 6 are moved out of the housing 1, and then the operator can take out the primary filter 5 and the medium filter 6, so as to clean the surface of the primary filter 5 and the medium filter 6;

[0048] After cleaning is completed, the primary filter screen 5 and the medium efficiency filter screen 6 can be inserted into the interior of the shell 1 again, and then the left sides of the primary filter screen 5 and the medium efficiency filter screen 6 will contact the right side of the push plate 30, and push the push plate 30 and the hinge plate 31 to move, and then the hinge rod 29 will push the hinge block 28 and the slider 26 to move toward each other, and then the slider 26 will squeeze the spring 27, and then the limiting hole 22 at the top of the primary filter screen 5 and the medium efficiency filter screen 6 can be aligned with the limiting block 21, and then the motor 18 can be driven again to make the gear 2 19 rotate in the opposite direction, and then the push rod 1 16 will pull the moving rod 13, the connecting plate 1 20 and the limiting block 21 to descend, and then the limiting block 21 will enter the interior of the limiting hole 22 again, thereby fixing the primary filter screen 5 and the medium efficiency filter screen 6, and then the primary filter screen 5 and the medium efficiency filter screen 6 can continue to perform filtering work, and finally complete the operation process.
